Question Need help

Hey guys,
We need the stock axle back for a GXP. I took hers off and ran single chamber flowmasters with dual 3" tips. Looks stock but is Loud. Interior Drone is horrible. Over the last year we lived with it. Now shes switching cars with her mom and we need it quiet again. If anyone has a set id like to buy them from you. Prefer as much of a complete setup as possible. Maybe with the whole Y pipe intact? Let me know what you have.

I have the full stock cat back system. That would be a fortune to ship though!

well if you want to sell it cut it up in pieces and see what you can do to ship it. Ill pay shipping of course. How much would you want for it? I really only need the Y pipe to Tips. catback to y pipe section isnt needed.

Let me take a look at them and see how it looks. I just put the Magnaflow Catback System on mine, but I didnt really look at the old one when I took it off. It may have had aftermarket mufflers.

I will let you know as soon as I get up to the cabin to look at it again.

Just go buy some walker stock replacement mufflers from autozone. They will clamp to any pipe...problem solved.
